Title: Gas discharge indicator with auxiliary anodes - has perforated plates with etched holes, between cathode and anode, reflective on cathode side
Inventor: WALTER KARL-HEINZ DIPL ING
IPC: H01J61/92
Filed: 1979-06-29
Abstract: The gas discharge indicator device with an anode (1) and cathode (2) mounted on glass plates, has a stack of perforated plates (3) between them, acting as auxiliary anodes. These are suitably insulated and spaced apart, and are connected to the junction points of a series of resistances forming a chain and connected to the power supply across the anode and cathode. These auxiliary anodes do not effect the gas discharge between anode and cathode, but the size of the holes, which can be etched into the plates does control the gas discharge. These plates are thicker in the region of greater voltage drop. The surface of these plates towards the cathode are reflective. In one design, there are glass fibre layers between these plates, which do not cover the perforations, with the fibres parallel to their surface. The fluorescent screen is also on a glass fibre layer.

Title: Electrical switching circuit programming - employs cams spaced by discs on shaft and held by spring pressure
Inventor: STERCZYK ALEXANDER ING GRAD
IPC: H01H19/62
Filed: 1979-07-27
Abstract: Rotating discs form cams to operate electrical switch contacts in a repetitive or programmed sequence of operations. The cams are released to allow the positions to be set. In order to maintain settings on the other cams a spring provides a permanent force. A control shaft (1) is mounted between supports (2, 3) and carries cam discs (7) between a spacer plate (5) and a support ring (6). These cams are interspaced with spacing discs (8) fixed to the shaft and supporting the cams. A pressure spring (10) between two support rings (6, 9) allows the sliding ring (9) to provide permanent pressure on the cams. A supplementary spring (17) acting against the spacing plate on a shoulder (4) on the shaft assists the action of the main spring. Action of the supplementary spring is suppressed by a screw (20) to allow the cams to be positioned.

Patent DE-2938845-A1 (DE)
Inventor: WYNN NICHOLAS PATRICK DIPL ING
IPC: C22B3/30
Filed: 1979-09-26
Abstract: Ammoniacal liquors (1), in which nickel, copper and other metals are dissolved, are subjected to countercurrent extraction in at least two stages (2, 3) with the aid of an organic solution (4) in order to remove the copper at least virtually completely, together with some of the nickel. A washing appliance (7) is used to separate ammonia from the laden organic solution by means of dilute sulphuric acid. A three-stage extraction appliance (10, 11, 12) is employed to extract nickel from the solution by means of a sulphuric acid stream (13) in countercurrent thereto. The resulting, weakly acidic nickel sulphate solution (14) is heated, and nickel sulphate is crystallised in a vacuum evaporation crystalliser (16). From the copper-laden organic solution copper is removed in a countercurrent extraction appliance (19, 20) by means of a sulphuric-acid solution, and metallic copper is produced from this aqueous phase in an electrolytic system (22). From the electrolytic system (22), most of the sulphuric acid solution is returned to the extraction appliance (20, 19), and a small portion is used in the washing appliance (7) for removing the ammonia from the laden organic solution. The organic solution (4) free of copper and nickel is returned into the liquor extraction appliance (3, 2), so that the organic solution in a closed circuit flows through all the extraction appliances (3, 2; 7; 10-12; 19, 20). The process provides for economical production of metallic nickel owing to the simultaneous extraction of copper and part of the nickel directly from the ammoniacal liquor at the site of the ore processing plant. The otherwise required, laborious selective removal of the copper prior to producing the nickel is no longer required, as the nickel carbonate conveyed to the refinery is free of copper. A further improvement is achieved, in addition to the production of metallic copper, by producing pure crystalline nickel sulphate for nickel electroplating. <IMAGE>

Abstract: In the lubrication device, a lubricating oil pump (13) is provided which pumps oil into a manifold (15), to which an adjustable overflow valve (16) for control of the oil pressure is connected and from which oil feed lines (23) branch off, into each of which an oil feed control device (24) is inserted. Each oil feed control device (24) is designed in the nature of an injection valve and has a valve needle (27), which by way of a pressure piston (28) is constantly acted upon in the closing direction. The valve needle (27) also has a closing element interacting with a valve seat and a control piston part, which to the fore defines an opening pressure chamber (47) and to the rear a closing pressure chamber (48). A gas pressure transmission line (49) branching off from the cylinder chamber is connected to the opening pressure chamber and at least one differential pressure line is connected to the closing pressure chamber (48), which latter line also branches off from the cylinder chamber, approximately on a level with the oil outlet ducts (41). By virtue of this opening arrangement, gas pressure differentials between the upper and lower sides of the individual piston rings (6, 7, 8, 9) can be utilised for opening the valve needle (27), in order to inject lubricating oil accurately into the chambers (10, 11, 12). <IMAGE>
